British & Irish slang

British and Irish slang covers Cockney, Multicultural London English (MLE), Scouse, Geordie, Yorkshire, Brummie, Glaswegian, Welsh, West Country, and Irish English. The throughline is regionalism — most terms identify the speaker's city within a postcode — and a tradition of euphemism, understatement, and intensifier inversion (bare for "very", proper as universal qualifier). MLE, the dominant strain among under-25s, fuses Caribbean patois with Cockney and South Asian English. Signature exemplars: innit, bruv, peng, craic, knackered. The category leans urban (London, Manchester, Dublin, Glasgow) and skews Gen Z for MLE, all generations for regional dialects. Platform: oral, with strong representation on UK Twitter and grime/drill lyrics.
